Full Stack Developer & Automation Specialist | Transforming Ideas into Scalable Digital Solutions | Bridging Web Technologies with Robotics & IoT Innovation
I'm Dennis, a passionate Full Stack Web Developer and Automation Engineer with over 5 years of experience creating innovative digital solutions that make a real impact. Born in Brazil and currently based in Nairobi, Kenya, I bring a unique global perspective to every project I undertake.
My journey began at Universidade de São Paulo, where I discovered my love for systems analysis and development. This passion led me to Kenya, where I earned First Class Honors in Computer Science from the University of Nairobi, specializing in Software Engineering with a focus on microservices architecture.
Currently serving as Senior Full Stack Developer at Safaricom PLC, I've had the privilege of leading transformative projects like the M-PESA Business mobile application, which resulted in a 43% increase in business transactions. But my expertise extends far beyond traditional web development – I'm equally passionate about robotics, IoT integration, and automation systems using Arduino, Raspberry Pi, and cloud technologies.
What sets me apart is my ability to bridge the gap between web development and physical world automation. Whether it's creating a telemedicine platform with IoT device integration that earned 500+ GitHub stars, developing smart building automation systems, or building e-commerce platforms that handle 10,000+ concurrent users, I thrive on solving complex technical challenges.
I'm deeply committed to community development, mentoring junior developers at Moringa School and co-organizing the Nairobi JavaScript Community. I believe technology should be accessible and empowering for everyone.
My technical arsenal includes modern JavaScript frameworks (React, Angular, Vue.js), backend technologies (Node.js, Django, Python), cloud platforms (AWS, GCP, Azure), and embedded systems programming. I'm certified in AWS Solutions Architecture, Google Cloud Development, and MongoDB, constantly staying ahead of technological trends.
When I'm not coding, you'll find me contributing to open-source projects, participating in hackathons, or exploring Kenya's beautiful landscapes through hiking. I'm fluent in Portuguese, English, and Spanish, with growing proficiency in Swahili.
